My new choice for MEX
Switched to StR from the 4S. Nicer room and better service. I'm in MEX for business only, but find that this meets my needs. In particular, I really appreciate the quality of the room service food (which is surprisingly difficult for most luxury hotels to do well). I always arrive late at night and need to do a bit of work so room service is the only choice for the first night. I have never been disappointed.
Otherwise, it's a standard StR in a bland modern building.
